Man this relay is ugly but it works.
After talking with Jez - Morning.Star about coils and magnets, I decided to try to roll my own relay using cardboard, paper and fasteners.

Man this relay is ugly but it works.
Looks like I might have a use for relays with my #The Cardboard Computer - IO is my name project after all. I am looking into ways to interface IOs output to a converted typewriter and need isolation while still using materials/parts that are on hand here in my secret lab :-) Need 16 SPST relays, just need to get the coil current demands down to a manageable level.
Here is the coil for relay number 2. Using double thickness of cardboard at each end and turned 90 deg. for strength.
The counter weights for breaking the contact will be replaced by a spring or rubber band. Better core material is on the horizon.
As of this afternoon, IO and the printer both are using the relay as isolation and working well.

Thank you Horst. As rough as this construction is, it still works months later without needing any adjustments :-)
Ok, so how are U going to interface this with the main frame?
Mark will rip his house's electrical wiring to get enough wires.
Let's hope it's enough.
Haha, you know that's not too far from the truth :)
Not far from the truth Yann :-) I plan on treating the panel as ROM and still need to wire up the panel read logic. Each pad is one nibble and should track with the PC. Jez has recommended that I could try wiring it as a stack and shift four bits as needed for reading so could go either way :-)
Sorry for the loooooooooooong delay, not sure if the relay will find a use on IO. I might find a place for it later :-)
So you cheated and you jumped out of the boat after the end of this episode ?
I'll just leave this here --> https://hackaday.io/project/11914-relayreprap

Oh yes, I had already liked and followed the Reprap relay :-) thats one very well made relay :-)
